Seven Mistakes Done While Working With Hydraulic Equipment

Maintenance is a critical element to ensure any machine’s longevity. Even the most seasoned hydraulic machinery operators can botch it up, if they tend to overlook some critical factors. While working with hydraulic equipment, the user has to keep in mind some points.   Read on to discover the mistakes that can be sometimes committed by even an experienced user.

Forgetting to change the filters

Most experts change the oil filters according to a schedule. However, it is advisable to check the filters manually before changing. When the hydraulic filters are changed according to a strict schedule, then chances are abundant that the operator might end up either under utilising or overusing them. It is better to check the filter every now and then to know the level of dirt clogging it.

Whenever, the operator notices the density of dirt is heavy then it becomes advisable to change the filters. If done otherwise, the dirt will pass through the filter and jeopardize the performance of the equipment.

Forgetting to change the oil

Changing the hydraulic oil depends upon two factors:-

1.    Reduction in the additive package
2.    Debasement of the base oil

Both these factors depend upon the hours of work done by the machinery. However, replacing the oil squarely on the basis of hours of service rendered by the equipment is incorrect. Proper oil analysis must be done before throwing the oil tin in the trash barrel.

Running hot

High temperature kills even the most advanced hydraulic machines. The most affected components of a hydraulic machine – when overused – include double acting hydraulic cylinder, Hydraulic AC&DC Power Pack, Piston, hoses, pumps, seals and oil itself.

Proper know how of the technology is evident for users before beginning to work with a hydraulic system. Also, the knowledge of operating as well as maintenance is necessary for every hydraulic machine operator.

Guide To Select The Best Hydraulic Fluid

The present-day working environment overtly demands hydraulic systems to operate at high temperature, pressure and speed.  Such an ideal pressure, speed and temperature aid equipment to work to the best of its abilities. All such idealities are created within a system if it is lubricated using the best hydraulic fluid. With so many significant products (HydraulicRams, Hydraulics Cylinder, Manifold Block, etc.) running on the technology, the need to select the best fluid has become urgent.

A first-rate hydraulic fluid:-

•   Enhances operational efficiency of an equipment
•   Fosters operational performance
•   Minimizes the equipment’s wear
•  Lets the machinery withstand the harshest of working atmospheres

For performing such diverse roles, the fluid must have excellent physical and chemical properties to deal with the duty cycle’s rigorousness as well as environment’s hostility. Owing to its high importance, there are certain steps that help buyers select the best hydraulic fluid.

Determine the system’s pump and its required viscosity grade

Do not expect each of the hydraulic machines to have a common pump design. The age of innovation in technology has paved way for building fresh pump designs – piston, vane and gear (external and internal). Each pump design helps a hydraulic machine perform a specific task. Based on the design of the pump, it is determined as to which fluid (of a specific viscosity grade) has to be used.

Choose fluids as per the function which hydraulic equipment performs

Smooth operations of any equipment are promised by the quality of the hydraulic lubricant it uses. The chemical composition of the fluid is modified as per the function of machinery. The type of fluid facilitating heat transfer might not be apt to ensure optimal power transfer. For example, a synthetic-based fluid can handle drastic pressure swings and temperature fluctuations. However, the same fluid is not a great choice if the equipment’s application has a risk of fire; for such an application a water-based fluid is apt hydraulics cylinder.       

Practicing excellent lubricant selection is meant to give the machine longevity. 

What is Hydraulic Fracturing?

The chances of anyone mishearing the word ‘fracking’ are thick; resulting in raising eyebrows toward the manners of the speakers. Nevertheless, if the word is heard correctly, you will know it is among the significant ways of extracting oil and natural gases from oil shale. Referred to as hydraulic fracturing, the process came into existence in 1903, but it took close to 50 years to use the technique commercially. The entire oil extraction procedure has undergone a sea change with the advent of hydraulic fracturing.

The working of hydraulic fracturing

The process of hydraulic fracturing is initiated by pumping the liquid via a well to an underground shale deposit; this liquid creates immense pressure on the shale, causing it to break and release oil or natural gas. The most preferred liquid agent to be used in the process of fracking is water; however, sometimes crude oil, diesel oil, kerosene or diluted hydraulic acid can be used. Whenever, water is used as the liquid during fracking, it has to be mixed with certain chemicals and gaur, giving it a glutinous property.

Which parts of the world use hydraulic fracturing?

The gains from fracking have been aplenty. Some parts of the world that extensively use hydraulic fracturing process are the UK, Columbia, Argentina, Indonesia, Russia, Venezuela, Romania, Brazil, France and parts of the US. Being an indirect benefit, hydraulic fracturing has helped creating employment opportunities in several sectors such as hospitality, construction, engineering & surveying, equipment manufacturing, and electromechanical actuators.

By blending fracking with other technologies, the extraction of oil and natural gases from oil-bearing shale has become simpler and more profitable. The supporters of hydraulic fracturing assert that the process is, by far, the best natural gas and oil extraction technique, which is changing the face of global Energy industry.  The fracking process has opened the doors to oil and gas reserves that were earlier unreachable.

Everything You Wanted To Know About Hydraulic Cylinders

Hydraulic Cylinders

A hydraulic Cylinder is a mechanical actuator that uses the force created by a pressurized liquid in a sealed container. The hydraulic cylinders have a variety of application such as in manufacturing machines, heavy construction machines and garbage dump trucks. The fluid used in these cylinders is basically oil. The back and forth movement of the piston inside the cylinder barrel exerts pressure on the fluid and thereby produces force which is about ten times greater than the force exerted on the fluid. A hydraulic cylinder can be divided into following parts:  

Cylinder barrel: The main cylinder body is called cylinder barrel. Its main function is to keep the cylinder pressure intact.

Cylinder base or cap: Enclosed end of the cylinder is known as the cylinder base or cap. 

 Cylinder head: The main function of the head is to enclose the pressure chamber from the other end.

Piston: The back and forth moving object inside the cylinder barrel is called piston. Its function is to vary the pressure inside the barrel.

Piston rod: Piston rod is basically a hard piece of chrome plated rod attached with the piston that extends from the cylinder to the end of rod-head.

Seal gland: seal gland is fixed at the cylinder head to prevent the leakage of pressurised oil and to keep the pressure intact within the barrel.

There are a lot of hydraulic cylinder manufacturers in the market that manufactures different types of hydraulic cylinders with different operating pressure. Based on its components and specifications, the hydraulic cylinders can be classified into Plunger Cylinders or Ram Clylinders, Telescopic hydraulic cylinder
 or Mulstistage Hydraulic Cylinders and Cable Cylinders. 

With of so many choices available in the market, one might get confused while selecting the appropriate hydraulic cylinder. In order to select an appropriate cylinder one must consider the specifications such as bore diameter, maximum operating pressure, rod diameter and stroke or the distance traveled by the piston.

Guide To Choose The Best Hydraulic Cylinder

 

Ever wondered how the gargantuan equipment - primarily found in construction sites and other manufacturing facilities - meant to lift, push, dig, drill or grade? The component helping such an equipment to do its job effortlessly is hydraulic cylinder. Also known as linear hydraulic motor, the hydraulic cylinder is designed to yield unidirectional force via performing a one-way stroke. The process of choosing a hydraulic cylinder might seem mundane and unimportant at times; nevertheless, it is imperative to begin the selection procedure with a fresh approach.

Focus on the size of the bore

The bore size of a Hydraulic cylinder is significant. Don’t ever confuse the bore size with Outside Diameter (OD); since the OD is half-inch wider than the bore size. Now the question is why to focus on the bore size? Well, operating pressure that’s needed to perform the job squarely depends on the bore size of a hydraulic cylinder; the larger the bore size, the higher the pressure a cylinder takes.  Further, the force required to carry out industrial applications also drives the process of determining the required bore size.

Choose the mount

The mounts of a hydraulic cylinder can be categorized into two parts – straight line and pivoted. The question of choosing the right mount involves answering a simple question – in which direction the size of load will go? If the load has to be moved via an arc, then select pivoted mount; however, when the movement of load is in linear direction, select a straight line mount.

Keep work conditions in mind

Determining the exact environmental conditions is of import while choosing a hydraulic cylinder. The overall temperature in which the cylinder will operate helps in selecting its materials, finishes and seals. For example, select a stainless steel hydraulic cylinder, whenever it has to be used in food processing equipment.
